The Rosetta Mission

rosetta_descent_smallRosetta [feature starts at 5:27]
The Rosetta Space Mission has been in flight for ever 12 years and will be ending with a dramatic crash this Friday morning around 10:40 UT (4:40 am Mountain time) – it’s an event that will be watched and talked about by people around the world.

Rosetta is run by the European Space Agency, with contributions from NASA. The mission’s goals have been to study a comet to learn not only about how comets work, but what comets can tell us about the origins of the solar system, and perhaps connections to water and life. Rosetta was the first spacecraft to orbit and escort a comet as the comet approached and flew past the Sun, and Rosetta also carried a smaller spacecraft, named Philae, that performed the first landing on a comet.

The Rosetta mission has a very strong Colorado connection, since one of the instruments – an ultraviolet spectrograph called “Alice” – was operated from the offices of Southwest Research Institute right here in Boulder.We have three members of the Rosetta team here in the studio to talk about Rosetta, comets, and the rather exciting ending planned for the spacecraft in just a few days. Our guests are Andrew Steffl from Southwest Research Institute, John Pineau from Stellar Solutions, and John Noonan who is a recent astronomy graduate from the University of Colorado and is working at Southwest Research Institute.

There’s more information on the Rosetta Blog about how to follow the final events of the Rosetta mission.

Science of Booze // Rosetta Mission

Booze coverProof: The Science of Booze (starts at 8:09): Science journalist Adam Rogers, who claims to have taken a liking to single-malt whiskey when he reached drinking age, has immersed himself further into alcohol–particularly, the history and science of making booze, tasting it, and enjoying–or suffering—the effects of it. Booze is a big story: Indeed, making it was a key piece of the dawn of human civilization, as Rogers, who is articles editor at Wired magazine, shows in his inaugural book, called  Proof: The Science of Booze. Rogers talks with How On Earth host Susan Moran about fascinating fungi, sugar molecules and other key ingredients, as well as our human taste buds for alcohol. We have a couple of copies of Proof from our recent pledge drive, so call KGNU (303-449-4885) this week and pledge at least $60 to get your own copy.

Rosetta’s Rendezvous (start time: 17:40): How On Earth’s own Joel Parker, whose “real” job as a planetary scientist is a director at the Southwest Research Institute, a collaborating partner on the Rosetta Mission. The mission last week successfully became the first to land a craft on a comet flying through our solar system. It was a well earned landing: Rosetta left earth in March of 2004 and has traveled about 3 billion miles to rendezvous with this moving target. To learn more, read this recent Q&A with Joel in the New York Times.

Also, Shelley Schlender offers a special headline (starts at 3:39), an interview with CU-Boulder’s Dr. Kenneth Wright, an integrative physiologist, about his new study offering new clues about why shift work can lead to extra weight.
